Windows 10 end of support
Support for Windows 10 ended on November 14, 2025, meaning the company is no longer providing security updates, bug fixes, features, or technical support. To continue receiving critical security updates (only), you must enroll your computer in the Extended Security Updates (ESU) program.
Also, remember that this lack of updates will leave your system vulnerable to security threats and may decrease its performance.
Furthermore, since the software giant no longer provides updates, you should upgrade to Windows 11 or another operating system, such as Linux Mint, or plan to purchase a new device.
According to the company, all versions of Windows 10 have already reached the end of support, including:
- Version 1507 (RTM)
